The SRM-3 is a triple-tube short-range missile launcher mounted on battle armor suits. SRMs were already one of the most powerful weapons available for conventional infantry, and so following the introduction of battle armor they quickly became a favorite weapon for the new suits. More bulky than the portable launchers carried by infantry, the reliable SRM-3 benefits from the advanced fire controls and stability provided by battle armor while remaining smaller per tube than vehicular launchers.[3]

There are drawbacks to the smaller size of the launcher, first of which is that it lacks the storage space and alternative loading mechanisms to use most specialty warheads, limiting SRM-3s to firing Inferno, Torpedo or Multi-Purpose Missiles. In addition unlike larger launchers there is no ability to "cross-feed" missiles from one firing tube to another. Thus if one of the tubes was damaged, those missiles tied to it could not be fed to another tube and fired. Enhanced targeting gear like Artemis IV also cannot be connected to the launcher.[3]
